The Role We’re looking for a Growth Software Engineer to join our cross-functional Growth teams. You’ll blend full-stack engineering with experimentation - shipping code that directly moves acquisition, activation, and retention metrics. You’ll work closely with Product Managers, Designers, and Data Analysts to ideate, build, and measure experiments - from SEO and onboarding flows to referral loops and pricing tests - all while maintaining high technical standards in our MERN + TypeScript codebase. What You’ll Do Design, build, and ship growth experiments end-to-end - from hypothesis to measurable impact. Work across our stack (React, TypeScript, Node.js, MongoDB) to deliver experiments and potential big-bet features - anything needed to move the needle. Translate data into code: partner with Product and Data to identify insights, prioritise opportunities, and build solutions that move key funnel metrics. Optimise user journeys - activation flows, conversion funnels, and re-engagement loops. Instrument and measure everything: implement analytics, event tracking, and A/B test frameworks. Get things shipped fast - with just enough structure to keep the code clean, maintainable, and ready to scale. Stay curious: research new tools, frameworks, and techniques to enhance velocity and impact. Skills & Requirements: Must-Have 5+ years of software engineering experience (full stack). Strong proficiency with React , TypeScript , and modern front-end tooling. Backend experience with Node.js , Express , and MongoDB / Mongoose . Understanding of scalable application design and clean architecture principles. Experience with A/B testing , feature flags , or experimentation frameworks. Comfortable using tools like Amplitude, Segment, and GrowthBook to track impact, manage feature flags, and inform decisions. Must have a bias for action - able to move fast while keeping code reliable through smart testing, reviews, and documentation. Nice to Have Familiarity with growth engineering principles (funnels, loops, retention mechanics). Experience working closely with Product and Data teams to interpret and act on insights. Knowledge of SEO , onboarding optimisation, or internal growth tooling. Experience using AI tools (Cursor, Claude, MCP’s, ChatGPT, etc.) to improve engineering velocity. Understanding of UX, accessibility, and performance optimisation About You You’re curious and data-driven , always asking “why?” before “how?”. You’re excited by rapid iteration and measurable impact. You collaborate naturally across disciplines and communicate clearly. You take ownership - from shaping experiments to seeing them through to production. You balance speed with technical excellence - pragmatic, not reckless.
